ObjectiveTo introduce the role of three dementional computed tomograph (3D-CT) for patients underwent transcatheter aortic valve implantation (TAVI) procedure in perioperative evaluation. MethodsFrom April 2014 to June 2015, we retrospectively analyzed clinical data of 28 patients with severe aortic stenosis underwent successful TAVI procedure using new second-generation device, who were enrolled in this study including 12 males and 16 females at mean age of 72.8±4.5 years. We used 3D-CT to get the perioperative relative evaluation, including valve morphology and calcification degree, annular diameter, aoronary ostium height, ascending aorta, aortic sinus diameter, left ventricular-aortic angle, optimal intraoperative angiogram projection angle. Based on the evaluation by 3D-CT image, the prosthesis size, balloon size, best intraoperative imaging projection angle and approach of apex were then chosen. ResultsAll patients with severe aortic stenosis underwent successful TAVI procedure with mean logistic Euro-SCORE I:26.2%±7.9%. CT image revealed that mean aortic annular diameter was 24.6±1.8 mm with mean valve prosthesis size 25.8±1.1 mm and pre-dilation balloon size 23.1±1.2 mm and 76.8% patients were of tricuspid aortic valve with severe calcification and 25% patients were of asymmetric calcification. Optimal intraoperative angiogram image was achieved in 92.9% patients with the help of preoperative CT image. There was a statistic difference in mean transvalvular gradient after valve implantation (54.1±15.3 mm Hg vs. 13.1±8.5 mm Hg, P<0.05). And there was no mortality or severe complication postoperatively. Conclusion3D-CT image palys an important role during perioperative evaluation of TAVI procedure and it can be helpful for Chinese doctors to operate TAVI successfully.
Objective To explore the perioperative management of the coexisting diseases for the elderly patients with gastric cancer. Methods The clinical data of perioperative management for coexisting diseases in 528 patients with gastric cancer over 70 years old treated in the First Affiliated Hospital of China Medical University from March 1980 to November 2008 were analyzed retrospectively. Results The main coexisting diseases included cardiovascuclar disease (259 cases, 49.05%), respiratory disease (161 cases, 30.49%), diabetes (72 cases, 13.64%). Adjusting blood pressure and blood glucose, improving cardiopulmonary function, and hepatic and renal function were mainly given. The common postoperative complications included intestinal obstruction (10 cases), pneumonia (10 cases), reflux esophagitis (9 cases), functional evacuation disorder of gastric remnant (7 cases), and anastomotic leakage (5 cases). Ten patients died during perioperative period: 6 died of heart and lung failure, 2 of acute myocardial infarction, 1 of anastomotic leakage, 1 of intestinal obstruction. Conclusions The common coexisting diseases in the elderly patients with gastric cancer are hypertension， bronchitis and diabetes. Complete assessment of the patient’s general health before operation and intensive perioperative management of the coexisting diseases not only can decrease the risk of surgical procedures， but also decrease the incidence of complication and perioperative mortality.

ObjectiveTo evaluate and summarize the perioperative management experience of living related liver transplantation (LRLT). MethodsA retrospective analysis was made in perioperative management of 13 cases undergoing LRLT (15 times operation, including 2 cases of liver retransplantation) in our department from January 2001 to December 2002. ResultsAll the operations were successful. All the 13 donors were followed up regularly, 12 donors were uneventfully recovered after operation and 1 donor suffered from bile leakage due to T tube. The survival rate of recipients, who achieved longterm survival at 2 months to 2 years, was 92.3%(12/13); the survival rate of graft was 86.7%(13/15). One adult recipient with Wilson’s disease died of serious rejection on the 72nd day postoperatively. Two cases suffered from embolism of hepatic artery, one case received reduced size cadaveric liver retransplantation, the other case received liver retransplantation from cadaver, and they both achieved longterm survival after retransplantation. The other complications included: 1 case of serious rejection, 2 cases of ARDS, 6 cases of infection of microbe, 7 cases of serious hydrothorax, 1 cases of leakage of biliary tract, and so on. ConclusionPerfect preoperative management, which composes one of the key parts of LRLT, is critically important for both donor and recipient.
Vague preoperative localization and ectopic parathyroid often lead to the failure of operation in primary hyperparathyroidism. From Jun 1989 to March 1998, 11 cases of primary hyperparathyroidism had been treated surgically in the general surgery department of our hospital. Of them, 10 cases were operated successfully with the pathological diagnosis of adenoma and one parathyroid removed was reported normal. Preoperative localization, the knowledge of ectopic parathyroids, careful exploration during operation and the postoperative medical treatment are important for the perioperative management. Postoperative followup has emphasized to benefit the treatment in primary hyperparathyroidism.
Perioperative management of 58 hypertensive patients suffering from surgical disease is reported. We emphasize that before operation the blood pressure should be adequately controlled, and heart function promoted. It is safer that the diastolic pressure is controlled under 14 kPa before operation. During operation we strictly observe the change of the blood pressure and manage it in time. Analgesic and antihypertensive agents are used after operation.
Abstract： Objective To summarize surgical experiences and explore risk factors of patients undergoing repeated heart valve surgery. Methods Clinical records of 325 consecutive patients who underwent repeated heart valve surgery from January 1998 to December 2008 in Changhai Hospital of Second Military Medical University were retrospectively analyzed. There were 149 male patients and 176 female patients with their average age of （47.1±11.8） years. Following variables were collected: preoperative morbidity， heart function， indications and surgical strategies of repeated heart valve surgery， postoperative mortality and morbidity， which were compared with those clinical data of patients who underwent their first heart valve surgery during the same period. Multivariate logistic regression was used to determine risk factors of perioperative death of patients undergoing repeated heart valve surgery. Results The main reasons for repeated heart valve surgery were mitral valve restenosis after closed mitral commissurotomy and new other valvular diseases. Postoperatively， 28 patients died in the early-stage with the overall mortality of 8.6% （28/325）. The main reasons of in-hospital death included low cardiac output syndrome （LCOS）and acute renal failure. Compared with patients undergoing their first heart valve surgery， patients who underwent repeated heart valve surgery were more likely to have chronic obstructive pulmonary disease （COPD)， New York Heart Association (NYHA） classⅢ-Ⅳ， and atrial fibrillation， preoperatively. Their cardiopulmonary bypass time and aortic cross clamp time were comparatively longer. They also had more postoperative morbidities such as LCOS， acute renal failure and acute respiratory distress syndrome （ARDS）. Multivariate logistic regression showed that preoperative critical state （OR=2.82， P=0.002）， cardiopulmonary bypass time longer than 120 minutes （OR=1.13， P=0.008）， concomitant coronary artery bypass grafting （OR=1.64， P=0.005）， postoperative LCOS（OR=4.52， P＜0.001）， ARDS （OR=3.11， P＜0.001） and acute renal failure （OR=4.13， P＜0.001）were independent risk factors of perioperative death of patients undergoing repeated heart valve surgery. Conclusion Repeated heart valve surgery is a difficult surgical procedure with comparatively higher risks. Full preoperative assessment of the valvular lesions， proper timing for surgery and perioperative management are helpful to reduce postoperative mortality and morbidity.
Objective To explore the impact of recombinant human growth hormone （rhGH） on T lymphocyte subsets in patients with rheumatic heart disease during the perioperative period of heart valve replacement. Methods A total of 65 patients with rheumatic valvular heart disease who received heart valve replacement in Department of Cardiothoracic Surgery of Xiangyang Central Hospital from June 1， 2011 to March 31， 2012 were enrolled in this double-blind randomized controlled clinical study. All the patients were divided into 2 groups by random number produced by SAS software：the trial group and the control group. There were 35 patients in the trial group including 19 males and 16 females with their average age of 50.57 years， and 30 patients in the control group including 16 males and 14 females with their average age of 49.87 years. Apart from routine cardiac glycosides， diuretics， glucose-insulin-potassium solution， and postoperative anti-infective therapy， patients in the trial group also received subcutaneously injection of rhGH 5 U （1 ml）daily from 1 day before surgery to 3 days after surgery， and patients in the control group received subcutaneously injection of normal saline 1 ml as placebo. Peripheral venous blood samples were taken in the morning 2 days before surgery and 1 st， 3 rd， 7 th day after surgery respectively. Percentages of CD3+， CD4+， CD8+ were examined timely by flow cytometry and CD4+ /CD8+ ratio was calculated. Results In the control group， percentages of CD3+， CD4+ and CD4+ /CD8+ ratio on the 1st， 3rd， 7th postoperative day were significantly lower than preoperative levels， and percentages of CD8+ on the 1st and 3rd postoperative day were significantly lower than preoperative level （P＜0.05）. In the trial group， percentages of CD3+， CD4+， and CD8+ on the 1st and 3rd postoperative day were significantly lower than preoperative levels（P＜0.05）， while percentages of CD3+， CD4+， and CD8+ on the 7th postoperative day were not statistically different from preoperative levels （P＞0.05）; CD4+ /CD8+ ratio on the 1st postoperative day was significantly lower than preoperative level （P＜0.05）， while CD4+ /CD8+ ratios on the 3rd and 7th postoperative day were not statistically different from preoperative level （P＞0.05）. There was no statistical difference in preoperative T lymphocyte subsets between the trial group and the control group （P＞0.05）. The percentages of CD4+ and CD4+/CD8+ ratio in the trial group were significantly higher than those of the control group on the 1st postoperative day （P＜0.05）， while the percentages of CD3+ and CD4+ and CD4+ /CD8+ratio in the trial group were significantly higher than those of the control group on the 3rd and 7th postoperative day（P＜0.05）. Conclusion Use of rhGH can significantly increase T lymphocyte subsets expression， enhance body cellular immunity， and improve postoperative recovery of patients with rheumatic valvular heart disease during the perioperative period of heart valve replacement.

Besides, the future of esophageal surgery is predicted including minimally invasive surgery, the improving standard of lymph node dissection, neoadjuvant therapy application, postoperative life quality and prospective artificial esophagus. Meanwhile, the remaining problems are discussed.
Abstract: Due to complicated procedures and severe trauma, esophagectomy still remains an operation with high mortality and morbidity. With the advancement of anesthetic and surgical technique, as well as perioperative management, the mortality and morbidity after esophagectomy decreased significantly in recent years. The optimal perioperative management, normalized and individualized treatment was of importance in preventing postoperative complications and decreasing mortality after esophagectomy. This review summarizes the current state of perioperative management for esophagectomy.
